Was Klammern um JOINs angeht, ja, Access SQL ist damit sehr pingelig. Statt
FROM
actor AS a
LEFT JOIN film_actor AS fa ON a.actor_id = fa.actor_id
LEFT JOIN film_category AS fc ON fa.film_id = fc.film_id
LEFT JOIN category AS c ON fc.category_id = c.category_id
versuchen
FROM
(
(
actor AS a
LEFT JOIN
film_actor AS fa
ON a.actor_id = fa.actor_id
)
LEFT JOIN
film_category AS fc
ON fa.film_id = fc.film_id
)
LEFT JOIN
category AS c
ON fc.category_id = c.category_id
